Sei Network integrates Chainlink Data Streams, enhancing market data access for real-time DeFi applications and institutional adoption.

Chainlink Data Streams has officially launched on the Sei Network, enhancing its ability to supply timely and precise market data. This integration is crucial for real-time tokenization and decentralized finance applications, significantly improving the capabilities that Sei offers to both institutional players and the DeFi sector.

The Sei Network selected Chainlink Data Streams as its primary oracle solution, allowing for rapid access to low-latency, high-frequency market data. This development empowers a variety of DeFi and trading applications, which are increasingly important as institutional investment in blockchain technology rises.

Chainlink is further strengthening its offerings by partnering with the US Department of Commerce, aiming to transition economic data—such as Real GDP and the PCE Price Index—onto the Sei Network. This collaboration will provide users with access to critical domestic purchasing metrics, thereby enhancing the analytical capacity of Sei's platform.

Sei, recognized as a layer 1 blockchain, is designed with Ethereum Virtual Machine (EVM) compatibility that supports parallelized execution. The integration of Chainlink Data Streams enables Sei to feature sub-second price latency, high data accuracy, and liquidity-weighted bid-ask spreads. With a remarkable track record of facilitating over $25 trillion in on-chain transaction volume within DeFi ecosystems, this collaboration is a strategic move for Sei as it aims to attract more users.

The Executive Director of the Sei Development Foundation points out that the adoption of Chainlink Data Streams as the preferred oracle infrastructure is significant. This technology ensures that Sei has access to reliable and accurate price information. The ultra-low-latency delivery that Data Streams offers is integral for the high-speed demands of modern DeFi platforms.

Sei has already made considerable strides in processing billions of transactions and serves over 60 million wallets, holding its place as the leading EVM chain based on active users. Backed by prominent investors—including Multicoin, Jump, Coinbase Ventures, and Circle Ventures—the platform is well-positioned to leverage this integration for future growth and innovation.

In summary, the integration of Chainlink Data Streams into the Sei Network not only boosts its operational efficiency but also enhances its appeal to a rapidly growing base of institutional and decentralized finance users, marking a pivotal step forward in the blockchain landscape.
